PL/SQL :: Duplicate Rows Removal
Jul 3, 2012removing duplicate rows from a table.
We have the following table:
SSD@ermd> desc person_pos_history
Name Null? Type
------------------------------------------------------------------------ -------- ------------------------
PERSON_POSITION_HISTORY_ID NOT NULL NUMBER(10)
POSITION_TYPE_ID NOT NULL NUMBER(10)
PERSON_ID NOT NULL NUMBER(10)
EVENT_ID NOT NULL NUMBER(10)
USER_INFO_ID NUMBER(10)
TIMESTAMP NOT NULL DATE
We found out that few person_id's are repeating for a particular event (3):
select PERSON_ID, count(*)
from person_pos_history
group by PERSON_ID, EVENT_ID
having event_id=3
and count(*) > 1
order by 2
PERSON_ID COUNT(*)
---------- ----------
217045 356
216993 356
226198 356
217248 364
[Code]...
If we look at the 1st person id "217045", we can see that it is repeating 356 times for event id 3.
SSD@ermd> select POSITION_ASSIGNMENT_HISTORY_ID, POSITION_TYPE_ID, PERSON_ID,EVENT_ID, to_char(timestamp, 'YYYY-MM-DD HH24:MI:SS')
2 from person_pos_history
3 where EVENT_ID=3

222773 8 217045 03 2012-05-07 10:29:49
[Code]...
356 rows selected.It is safe to assume that the person id/event id with the earliest timestamp is the one that was loaded 1st, hence, the one we want to keep and the rest should be deleted.

Duplicate Sequence Number For Identical Rows
Jul 5, 2010I have a table:
Name
_____
Smith Street
Smith Street
John Street
Ed Street
Ed Street
Ed Street
and need to assign sequence numbers only when the record (Name) changes, e.g. :
Name Seq
_____ ____
Smith Street 1
Smith Street 1
John Street 2
Ed Street 3
Ed Street 3
Ed Street 3
I have experimented with row_number partition but then i just get the sequence returning to 1 when the name value changes.
If I grouped the records by Name I would like to have unique, sequential numbers: 1, 2, 3 but where there is the same name I would like the sequence to stop and the number to replicate?
SQL & PL/SQL :: How To Avoid Duplicate Rows From Being Inserted In The Table
Dec 21, 2009I have one table in which I want to restrict some records from being inserted. I don't want to put any checked constraints. e.g. consider following table
transaction(
id number primary key,
txn_date timestamp(7),
payee varchar2(40),
amount number,
memo varchar2(40),
ref_num number
)
I want to write SQL which should not inset duplicate record.
e.g.
I have written one as bellow:
insert into transaction
select 1, to_date('2009-12-12','YYYY-MM-DD'), 'Payee1', 12, 'Test', 212 from dual where
(select count(*) from transaction where txn_date=to_date('2009-12-12','YYYY-MM-DD') and
payee='Payee1' and amount=12)=0;
Can I use exists/not exists, which query will be more appropriate. (Please consider that fields which I am using to filter out the duplicate transactions does not contain primary key.)
Can I write such SQL. Or do i check for duplicate rows one by one and then filter the duplicate records.
